AVP- and OXT-mediated vascular reactivity in human umbilical vein. a, c Concentration-response curves of AVP-induced dose-dependent contractions in HUV (N = 20, n = 38 each group). b, e KCl-induced maximal contractions in HUV (N = 20, n = 38 each group). d, f Concentration-response curves of OXT-induced dose-dependent contractions in HUV (N = 21, n = 36 each group). AVP arginine vasopressin, OXT oxytocin, KCl potassium chloride, NP normal pregnancy, PE pre-eclampsia, HUV human umbilical vein. Error bars denote SEM. *P < 0.05; **P < 0.01. N number of participants, n number of HUV rings
